It is an excellent initiative. I hope some useful insights will come out of this project. Just FYI, and it’s completely based on my personal experience, stuttering depends heavily on the situation. I have a mild stutter. And that also shows up in the stressful situations. For example, if I record the script you provided in my room, I’ll probably not stutter at all. If I do it in front of a crowd, I’ll likely stutter a couple times.
